tories, ofwhich the following is a specification. My present invention relates to garbage erematories, the construction and advanta es of which will be hereinafter set forth,

' reference being had to the annexed drawings, wherelnz I 1 igure 1 1s a longitudinal sectional view of the apparatus; Fig. 2 aside elevation of the rear portion thereof; Fig. 3 a transverse vertical sectional view, the left-hand portion being taken on the line 3-3 and that portion to'the right on the line 33* of Fig. 2.

Fi 4 a detail sectional view of the crush1ngrol s and belt; Fig. 5 a pers ective view of a portion of one o the crossars of the belt and it's attached links; and Fig. 6 a longi tudinal sectional view of a portion of the lower crushing-roll, one of the cross-b are, and

a the "attached links.

The'main object-of the invention is to provide means for positively feeding the 'garbage'between the crushing and expressing for preventing too great a rim rolls and to thereafter deliver the same, into the retort. A further object is to provide means for introducing fuel into the retort with the arbage, and toutilize the same conveyer ror ca 'ng the fuel and garbage. f A stil further object is tov rovide means from easing into the apparatus when thegarbage- 'opper isopened for the reception o a freshcharge' of material. a 1g;

. With these and other objects. in .view 'I will now describe the invention. I

Iii the main the invention embodies certain features of the constructionset' forth and claimed in Letters Patent No.1794,471, of-July 11, 1905; that is to say, two retorts, desi letters A and B, being located in with the two stacks C and D,

the hopper. The conveyor 18 com a series of bars L, which are secure it lugs nated bythe' employs ,said retorts t e lower portion of the main body of the structureand communicat-' 5 k. C .a ording a direct draft, while stack D gives an indirect draft and causes the products of I combustion to pass through the fire-tubes of the boiler E. A suitable blower, as in the former construction, will be employed, the air from said blower passing through a pipe F and being discharged beneath the grates gr: the retorts in .the manner best shown in 1g. 1.

The garbage or the like which is to be cremated-isplaced from time to time in a hopper G, which is provided with a swinging cover H; The hopper, as will be seen upon reference to Fig. -1, is provided with an inclined bottom I, which terminates at a point just above the conveyer-belt,"the construction of which will be hereinafter set forth in detail. The forward portion of the hopper is provided with a swinging apron J, w extends downwardly toward the conveyer and terminates at a point slightly above the 1pc or the purpose of heating the garbage when occasion requires. The swinging apron J prevents too great a draft from passing in throu h and t ere is but relatively little garbage in osd of or ears M that extend outwardly i the chain-links N (Fig. 5). As will be seen upon reference to Fig. 6, there are two chains composed of a series of links, as N, the bars being secured at each end to said chains.

The upper'crushing-roll, Ofis fluted and extends across the entire width of the chamber. P (Fig. 1) and the lower crushing-roll, Q, also extends across the entire Width of said chamber. The lower crushing-roll Q is, of the. form best shown in Figs. 4 and 6, the roll bein provided with a series of teeth or ribs R w 'ch pass up between the cross-bars L of the conveyer-belt.- Each end of the roll K through which steam is introduced the hopper when the cover is opened Q is provided with a flat surface S upon.95

which the links of the chains rest, the ribs R,

as before mentipned, passing) in between the -throughthe openings between thecross-bars the garbage cannot be forced through the belt, a though the expressed. liquidEm'ayfind free passage therethrough.

I the Wheel U,

I cross-bars L of the as the ribs Roi the Adjacent to the opening formed between retort B and the chamber P is mounted a roller '1, provided with a series of ribs or teeth which extend'lengthwise thereof and ass into the openings between the bars L: S aid roller-T is driven by means-of a wormworm V and an engineo'r motor W, the latter,by suitable caring, imparting motion to the worm, see ig. 2. This roller conve 'er-belt, and the ribs thereon, by reason of passing into the spaces between the .same by the action of the crushin -rolls O and Q. The end passes about an idler-roll X. Inasmuch lower roll'Q are always in mesh with the belt orconveyer, said roll is driven thereby, and through the gears Y and Z (Fig. 2) positive rotary motion is imparted e upper crushing-roll 0. By' the emt .th

pioyment of a conveyer or belt thus con- 3 structedthe garbage is positively fed in between the crushing-rolls so that all hard substances are broken, and the moisture (to a considerable extent) is expelled from the ceptacle A garbage and passes down into the liquid-re the chamberlP. If thewill not a'ss'between the-two rollers, either plain or uted, but by the employment of-the y 'conveyer-belt the garbage is taken from the connected witht e hopfir and positively passed beiween the crus ng-rolls, and from these rolls is dis= charged into the retort B, Where-it is consumed.

Located ab ovethe chamber P is a fuel- .rece'ptacle B, provided with an openin 'C thesize of -.door or valve D. sir'ablatcmix a certain amount of fuel with the garbage as it'is carried forward to. the retort B, and by regulating the size of the opening 0 the amount of fuel fed into the retort with. the garbage may be regulated as desired. Furthermore, the beltmay be used as a fuel-conve'yer, 'per se.

Inasmuch as the garbage is usually collected from a series of small receptacles, some means should be provided for removing.

the grease from the interior thereof, and to this end I have rovided a pipe E (Fig. 2) steam-space of the boiler; and through which the interior 'ofthe receptacles from which the. garbage is collected. The adhering grease will thus be'melted and may be emptied intothe hopper. '7 Y Inv order to re'vent the esca e of an fumes or odors fi om the chamber through the opening g'. or through hopper G, I provide a fiueroropening F (Fig. 1) which exforms in effect the driving member for the. derstood, of course, that it 1s conveyer, expel any garbage which may have been forced into the conveyer or belt at 1ts lower.-

tion of /same; a chamber situatediat a point in rear tends from the upper 'ortio'npf the chamber P into the fire-space '8' of the boiler. This 0 enin is-of such size as not to materially a cot t e draft through'the fire-tubes, but is sufiicient to cause an upward draft'from the chamber P, as indicated by the arrows in "%Vhile have shown the invention as 'applied to a portable cremato it is to be une upilyapplicable-to a'stationary lant, ian .the claims are not to be'restricte to. either form of apparatus.

Having thus described my invention, what 'Iclaun is:

1 Ida crematory, the combinationof a retort a hopper for the reception of garbage orthe like; a conveyer extending from the conveyer comprising two endless chains and a series of crossbars connected to said chains; a fluted, crushing-roll located above said convyer; a second crushing-roll situated below said conveyer, the lower roll being provided with a series of teeth extending and likewise having a fiat surface at each end upon which the chains hopper and discharging into the retort, said may rest; and means for driving said conveyer.
